摘要
以模拟集雨窖水为实验原水,通过改变电絮凝过程中的电流密度、通电时间、极板间距等因素值的大小,研究电絮凝在原水浊度去除中的的最优参数组合。得出影响浊度去除效果的各因素主次关系依次是:电流密度>极板间距>反应时间,当电流密度为18.89A/m2,极板间距为1 cm,反应时间为13 min时为电絮凝去除浊度的最优组合,浊度去除率为92.94%,同时对窖水中的CODMn、UV254也有一定的去除效果。
The collecting rain water was used as raw water in this experiment.The current density,electrified time,polar board spacing were changed in electro-coagulation process to search the optimum parameter for removal of raw water turbidity.The sequence relation of each factor one by one which affect the removal effect is current density>polar board spacing>contact time.When the current density was 18.89 A/m2,polar board space was 1 cm,contact time was 13 mins,which is the optimum combination in electro-coagulation process of turbidity removal.Removal rate of CODMn and UV254 was improved in rainwater collection while the removal rate of turbidity was 92.94%.
